DEVELOPMENT OF TRAVELLING WAVE PROPULSION MECHANISM WITH PERMANENT MAGNET VIBRATION MOTOR

Abstract

Recently, the autonomous underwater vehicles use screw propellers as propulsion mechanisms. However, the screw propellers generate bubbles and affect acoustic measurement. Therefore, in recent years, there have been many researches on propulsion mechanisms using travelling waves imitating the permanent magnet vibration motor. By using permanent magnets for the vibration motor, it can save power consumption and drive with high thrust. This propulsion mechanism can reduce the sound during propulsion. We produced a propulsion mechanism with travelling wave and evaluated its basic structure and characteristics from the experiment.
